NITE@ STATES DEVICE FOR CONTROLLING DRAWN IMPLEMENTS FROM THE SEAT F A TRACTOR.

Application tiled April 9,

.To all whom it may concern:

Be it known that I, Jol-1N A. HALL, a citizen of the United States, residing at Leba non, in the county of Warren and State of 5 Ohio. have invented a new and useful Device for Controlling Drawn Implements from the ySeat of a Tractor, ot which the 'following is a specification.

My invention relates to devices whereby the driver of a tractor may operate imple ments which are being drawn thereby from his seat on the tractor.

Notwithstanding the great and manifold advantages derived from the substitution ot' tractors for horses indrawing farm implements, there has been one important drawback. namely that an extra man has been required to run the tractor. That is, it has required one man to drive the tractor and another to operate the implement. This has been due to two principal causes: (l) implements are mostly madey to be drawn by horses, with the driver riding on the implement. The control devices are therefore placed convenient to the driver in his seat, which is frequently, if not in the majority of cases, located at the rear, so that the implement is between the driver and the horses, and (2) the hitch by which the im-V plement is attached tothe tractor separates the machines so tar that controlling devices ou the implement are beyond the reach of the tractor driver.

.The principal object of my invention is to provide mechanism whereby-the tractor driver can control the action of an implement, so that he can drive the tractor and -simultaneously operate the control mechanism. For example, when a grain binder is in operation it isnecessary to operate the bundle carrier periodically, to drop ott the bundles that have accumulated on the carrier and then setthe carrier to receive new bundles. One object ot my invention is to enable the tractor driver to operate the bundle carrier. Another example is in the case of a mower: It frequently becomes necessary to lift the cutter bar to avoid its striking a stump or other obstruction which might stall or even break the machine. It is mv object to enable the driver to lift the bar at will from his seat on the tractor as he formerly did when he rode on the mower. l Another object is to provide a mechanism for the stated purpose, of such character that it can be marketed as an .article of manu 1921. Serial NPO. l$60,110.

facture, to be applied by the purchaser to his own machinery, the mechanism being so constructed that it can be applied with substantially no change in the existing machines.

Another object is to provide a mechanism of such character that'it can be folded into a compact form, enabling it to be shipped in a comparatively small box, by express or even parcel post.

In the accompanying drawings,

Figure 1 is an elevational view showing my device mounted on a tractor hitch and connected to the bundle carrier mechanism of a grain binder.

Figure 2 is a plan view of the same parts as those shown in Figure 1.

Figure 3 is a view similar to Figure 1. but with portions omitted, showing the parts in the position they are allowed to assume to dump a load of bundles.

Figure 4 is a plan view of the carrier. showing a portion of my device with the parts in the position they occupy in Figure 3.

Figure 5 illustrates the arrangement ot the parts of. my device tor shipment, the` dotted rectangular frame surrounding the parts representing a box in which the parts are enclosed.

Figure 6 is a view taken on line 6-6 ot' Figure 1.

Figure 7 shows my device applied to a {onower for the purpose of lifting the cutter Referring now to the views concerned, l will first briefly describe the bundle carrier to which my device is attached, it being understood, however, that the carrier is not part of my present invention. Extending horizontally from the frame of the binder (not shown) are two angle iron bars 10, to which are attached a horizontal angle iron bar 11, this bar 11 being raised above the bars 10 by tubular spacers 12. through which the rivets 13 for holding the bars together pass. A number of carrier arms 14, are attached to the vertical member of the angle 11 by fixtures 15, which are so constructed that when the arms exten squarely from the bar 11, as in Figures 1 and 2, their ends are elevated as in Figure 6. so as to prevent bundles of wheat from falling oft of the carrier. while when the arms are swung, around., as in Figures 3 and 4, the arms drop and' allow' thel bindles to slide, ground. 14 are provided with rearward extensions, connected to a bar 16, which bar is moved longi tudinally to and fro to operate the carrier;V that is, to move the arms from one positionto the other. 'For movingthe bar lb' a round rod 17 is provided.A This rod is,`

journaled at 18 in the bar 11, and at 19 in a'bearing lfixed to` tlieframe ofthe binder. Adjacent to the bearing 19 the rod` is bent upward to forni a lever 20 for rocking; the rod. Close yto its bearing 18 .thel rod 17 is bent downward, forming;- a loop Q1, whicln acts asa crank,y `and `to which `a nifinan 22 islatta'ched.` the other end of the pitman being` connected to the bar 1 6. Normal operation of the carrieris effected through a rod 23 shown in dotted lines in Figure l, i

which is attached to the: end of the lever Q0 and `extendsvto an `,operating` lever `or, the like located near the drivers seat, notillustrated at the rear `of the hinder.

To couple the binder to a tractor a: tongue 30, commonly called ai hitch. is `attached to the binder, and at lthis hitch. is coupled to the tractor. Onlyfthe drivers seat and the draw head of the tractor are shown in the drawings5'thesebeing .in approximately their correct relative positions. I will now describe my device .whereby the Adriver of the'tra-ctor isenabled to operate the bundle i' carrier,1 thus dispensinuwith theinan who heretofore has been required in the drivers seat on thebinder:

On Athehitch I-mount a bracket consiste. ing ofa;'long..and a short upright, 32 and` 33, which are tied together ,byan oblique brace 34. A lever 35 is pivotally` attached to the upright 33a'nd at the upper end of the lever a pull rod 36 is pivotally attached. This, rod, passesV through a guide loop foi-inedon the endof theupright `32` and at its free end is provided with Aa handle 37..

A rod,38 is pivotally connected to the lever 35V and the other end of thisy rodlis'conf, nected to thelever 20. The rod23, shown,

in dotted lines `in` Figure 1. lmay be de# tachedand the `rod 38 connected in its place to,the levenQO. By means of'apin 39, which passes through the loop, ,and a notches 19in the ledgre of the rod,.therod-Bgmayl f be latched to thev upright in` any ,desiredj position. For the purpose ofvadaptingfthe rodi38 `to various implements it is inadey in twoparts so that its length may be va?` ried. i Y l r Itis obvious that the driven of the tractor, from his seat, can unlatch the handle and push it from-him, thereby swinging the carrieruarms tol the position shown in Figure 3, andlassoon as the bundles lhave'dropped ofi' hecan pull thev rodtoward him, restor ingr thelcarrier armste theirnormal 4positionsand by latching the pull rod 36 to the upright the carrier is maintained in no1"- mal condition, ready to? receive new bundles of grain, The attachment of the hitch to the binder is substantially rigid, and since the bracket to -which the rod 36 is attached is` fixed tothe hitch, it ,follows that the Vlatch 3941() of device is as'efl'ective `for holding' the bundle vcarrier in normal condition as is the regular mechanism for this purpose, carried by the binder.` That is, notwithstanding the handle? is brought within reach ofthe man sitting in the tractor seat,the efficiency of the bundle carrier,

andwthel facilitywith whichitican be manipulated, is fully maintained. And this is true whateverposition the tractor may occupy with reference tothe binder,even in turning a corner, for example,v y

The main advantage oinusing my ,devicev is, of cours'e,` that it dispenses with oneinan.

Another advantage is that the operation of the binder can be observed better from the tractorhseat than from the driyers seat on the binder. y This is Abecause most `oi: ythe mechanism of the binder is in front where it .cannotbe seen from the binder seat.

In Figure 7 my device is shown slightly modified `anda applied to a mower for the purpose of lifting the cutter bar.

The cutter bar is hinged at l-ilto portion 46 ofthe mower frame, 'and Vthrough medium of an.

arin- 47,. link 48., bell-cranlr 49,1ink 50, bellcrank 51 and rod 52, the driver of'lthe mowerjis enabledvto lift they cutter'bar by aleveradjacent tothe drivers seat. Usually there is a springjarranged to exert a pull on the rod '52,. in ,the direction of ,the arrow,lso that the weight ofthe cutter 53` is partially neutralized, Now to operate the cutterbarflrwith `,device I mount Ymyl bracket, the saine yas hasbeeii described, on the mowerhitch 60,'A The modification consists lin tying therlevers 35 and bar 381c- .s/ther 'bfv l'nkl S6 that liti bei .38 ,bev copies in` effect a` part, VQrj extension, of ythe lever: VIt funderstoodthat the handle 'adjacent to `the :tractor drivers seat. A and yit .is 'seen that ,by pulling thefh'andle 37 toward him 'Chfliiverfwill raise the lever 355-38a`and effectfjust thelsaine"result as a mani in` the. mowervseat wouldlwhen lie operatedfthe Ameehaifiism which a pull is exerted on the rod`52. In "eaclfi caserthe bell-crank lis rocked and the cutter'bar 53y vice can be arranged to operate the brakes onv the trailer. It has been seen that the device can be applied without changing, an implement, at least without change that cannot be effected by any "farmer, so the device can be sold separately trom either the implement 0r tractor, to be mounted by the purchaser in a manner to suit his own needs.

I do not wish to limitmyself to the particular structural features shown, as it is evident that various ways may be found to effect the purposes I have disclosed.

What I claim as new and desire to secure by Letters Patent isl as follows:

l. In a device ot the character described, the combination of a hitch for connecting a farm implement to a tractor, control mechanism on the implement, comprising an element which when moved in a characteristic manner is capable of operating said mechanism, a rod connected to said element and to a lever tulcrumed on the hitch, a substantially horizontal pull rod connected to said llever and provided at its free end with a handle, a guiding bracket mounted on the hitch, whereby said rod is supported with the handle within reach of the driver of the tractor while in his seat, and a notch and pin arrangement whereby to lock the rod to the bracket in desired positions.

2. A device for the purpose described, consisting of two uprights, one comparatively short and the other long, each provided with a fla-nge to be attached. to a tractor hitch; an oblique brace extending; from the long upright down to the short one, whereby the former is stabilized, a lever pivoted to the short upright, a rod pivotally attached to said lever, the tree end ot said rod passing through a. guide on the upper end of the long upright, a notch and pin arrangement for latching said rod in required positions with respect to the long upright, said lever and rod being capable of being moved into ay position in alignment with each other and into approximate align ment with said brace.

3. In a. device ot the character described, for the purpose of operating the control mechanism on an implement, which mechanism comprises an element to be rocked to and fro; a hitch to connect said implement to a tractor, means connecting the hitch to the implement at a point removed, laterally, from said rocking element, a lever fulcrnmed on the hitch, a rod extendingdiagonally from said lever to said element, said rod being pivotally attached to said lever and element, a pull rod connected to said lever, with its free end accessible to the driver of the tractor, and notch and pin locking means for locking the pull rod in various positions, whereby to hold said roel@ ingelement in any desired position.
